To all 'whom t may concern.'

Be it known that I, CHARLES H. SPEK- MAN, a citizen ofthe United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Radiator-Valve Connections, of which the following 1s a specification. 1 The objects of my invention are to provlde a cheap and simple form of valve for hot waterra'diators whereby the supply branch of the valve casing'may be connected to the inlet branch of the radiator and the outlet branch of the latter to the discharge branch of the valve casing, or the radiator may be cut oii' from the valve casing and the hot water caused to flow directly from the supply t6 the discharge passage thereof, and to construct the valve in such a way `that any back-flow'through the radiator will be prevented.

These objects I accomplish in the manner hereinafter'set forth, reference being had to the accompanying drawings, in which- 0 Figure l is a longitudinal section of a radiator valve constructed in accordance with my invention, the parts being shown in position to cause'circulation of hot water, froma the supply passage of the valve casing, through the radiator, and thence to the discharge passage of the valve casing;

Fig. 2 is a similar view, the parts being shown in position to cgt oti' the flow of hot water to the radiator and cause itto flow directly from the supply to the discharge passage of the valve casing;

Fig. 3 is a transverse section on the linev 3 3,

Fig. 4 is a'perspective view of the valve detached from the casing;

Fig. 5 is a longitudinal sectional view of a valve structure of modified form embodying some of the r,features of my invention, the parts being shown in position to cause How of water through the radiator;

Fig. 6 is a similar view showing the parts adjusted to cut off the radiator and cause the water to flow directly from the supply to the discharge passage of the valve casing;

Fig. 7 is an end view. looking in the direction of the arrow Fig. 5;-

Fig. 8 is a perspective' view of the valve shown in Figs. 5 and 6, and

Fig. 9 is a perspective viewof one of the elements of the valve casing shown in said figures.

Referring in the first instance to Figs. 1,

' 2,3 and 4 of the drawing,

the supply passage of the valve casing is represented at 1 and the discharge passage of the same at 2, these passages meeting one another in a chamber 4 across which extends a diaphragm valve 5 with edge anges 6 and 6a, this valve fitting snugly to the walls of the chamber 4 both at the flange edges, as shown in Figs. 1 and 2 and at the opposite sides, as shown in Fig. 3.

Communicating with the chamber 4 of the valve casing are passages 8 and 9 separated from one another by a transverse partition 10 which has at its inner end a downwardly extending liange 11, as shown in Figs. 1 and 2, the passage 8 communicating with the inlet passage of the radiator and the passage 9 communicating with the outlet passage of the same.

The diaphragm 5 bears at one side against the side wall 12 of the casing and at the other side against the inner face of a cap 13 which is screwed or otherwise fitted into an opening in the opposite side of the casing, said cap having a suitably packed bearing for a stem 14 projecting from the side of the diaphragm and provided with a square end 15 for the reception ot'` a handle or other means whereby it may be readily turned in one direction or the other.

The central chamber 4 of the valve casing has seats 16, 17, 18 and 19, the edge tianges 6 and 6a of the diaphragm 5 bearing, respectively, upon the seats 16 and 17 when the diaphragm is in the position shown in Fig. 1, and upon the seats 18 and 19 when the diaphragm is in the position shown in Fig. 2. When adjusted to the position shown in Fig. 1 the diaphragm serves to permit direct liow of the water from the supply passage 1 of the casing to the passage 8 and thence to the radiator, and from the radiator through the passage 9 to the discharge passage 2 of the casing, any direct How from the passage 1 to the passage 2 being cut off.

l/Vhen, however, the valve is adjusted to the position shown in Fig. 2, the diaphragm 5 serves to cut off flow from the passage 1 to the passage 8 and from the passage 9 to the passage 2, and provides for a direct flow from the passage 1 to the passage 2, thereby setting up a by-pass and cutting off the circulation of water through the radiator.

Owing to the provision of the relatively deep flange 6 at one edge of the diaphragm 5, said diaphragm can be Iadjusted to the position shown by dotted lines in Fig. 1, whereby, without checking free communication between the passages 9 and 2, the communication between the passages 1 and 8 may be reduced to such'an extent as to reduce the Volume of flow therethrough, thereby retarding the speed of circulation of the water through the radiator.

Should conditions be such, at any time, as to result in a tendency toward backflow of the water through the radiator, the water that would be drawn in through the passage 2 would be, to a large extent, trapped by the depending flange 11 on the partition 10 and normal circulation would speedily reestablish itself.

In the modification of my invention shown in Figs. 5 to 9 the diaphragm 5 turns on a longitudinal instead of a transverse axis and has formed in it downwardly and upwardly projecting pockets 20 and 21, the downwardly projecting pocket extending from about the longitudinal center of the diaphragm to one end of the same and the upwardly projecting pocket extending from said central point of the diaphragm to the opposite end of the same, as shown in Fig. 8.

To that end of the valve casing opposite the end havin the supply passage 1 and the bearingfor t e valve stem 14 is fitted a tubular plug 29. with projecting segmental ange 23, said plug providing a bearing for the adjacent end of the pocket 21, as

shown inFigs. 5 and 6. When' the parts are in the position shown in Fig.- 5 conditions are the same as in Fig. 1, and when the parts are in the position shown in Fig. 6 conditions are the same as in Fig. 2.

I claim:

1. The combination, in a lradiator valve,of

ya casing having supply and discharge passages and a chamber communicating therewith, a partition between said supply and discharge passages, a diaphragm interposed between the supply and discharge passages of the casing, and mounted so as to be free to swing about its axis, and an edge flange on said diaphragm coperating with the partition to permit of adjustment of said diaphragm so as to provide either a full or a. restricted flow through the supply passage of the casing, while permitting a Jfull flow through the discharge passage of the same.

2. The combination, in a radiator valve, of a casing having supply and discharge passagesa and a chamber communicating therewith, a partition between said supply and discharge passages, a valve member in said chamber and a flange depending at substantially a right angle from said partition said {iange presenting an abrupt face tc and serving to retard any back-flow through the casing.

In testlmony whereof, I have signed my name to this specification.

CHARLES H. SPECKMAN.
